Android 10 clipboard not working properly

Environment

Technology	Version
Flutter version	1.22.6
Plugin version	4.0.0+4
Android version	10

Device information: Pixel 2

Description

Try run simple code and check next steps:

1. Run app, wait for google.com is loaded
2. Go to other app where you can copy some text to your clipboard
3. Try paste it to test app in google search
   In this flow you will have nothing(

Check 2:

1. Open some app and copy some text to clipboard
2. Run test app, and try paste text from clipboard to goole search - yeah, this working fine
3. Switch by RecentApps to app with text, copy some other text to clipboard
4. Switch back to test app, try paste = you will see old text (clipboard is not updating on android 10)

After few hours spend to research module I found a little bit "hacky" way to fix this:
in file
{FLUTTER_SDK}.pub-cache\hosted\pub.dartlang.org\flutter_inappwebview-4.0.0+4\android\src\main\java\com\pichillilorenzo\flutter_inappwebview\InAppWebView\InAppWebView.java

add
onWindowFocusChanged(true);
at rebuildActionMode() function begin:

like this:

  public ActionMode rebuildActionMode(
          final ActionMode actionMode,
          final ActionMode.Callback callback
  ) {
    onWindowFocusChanged(true);
    boolean hasBeenRemovedAndRebuilt = false;

so chrome WebView will be notified for FocusChanged and will update data from clipboard

P.S. this is fast solution and not pretty good for use, but I need working WebView, maybe someone need too |./|

Thanks, this way it will resolve the problem!
Maybe it could be this:

onWindowFocusChanged(isFocused());

I'm going to add this fix with the next commit.

I'm newbie in flutter, and not fully understand view managment. But I see containerView, and I think this can be a solution:

if (containerView != null)
  onWindowFocusChanged(containerView.isFocused());

[pichillilorenzo]

yeah it seems good! thanks! maybe also:

if (containerView != null)
  onWindowFocusChanged(isFocused());
